ABSTRACT The woody bamboos (Bambusoideae) exhibit distinctive biological traits within Poaceae, such as highly lignified culms, rapid shoot growth, monocarpic mass flowering and nutlike or fleshy caryopses. Much of the remarkable morphological diversity across subfamily exists a single hexaploid clade, paleotropical (PWB), making it ideal to investigate factors underlying evolution in bamboos. However, origin biogeographical history PWB remain elusive, does effect environmental on their characters. We generated robust time‐calibrated phylogeny using nucleotide polymorphisms retrieved from optimized double digest restriction site associated DNA sequencing, explored evolutionary trends habit, inflorescence, caryopsis type relation including climate, soil, topography. inferred that started diversify Oligocene–Miocene boundary formed four major clades, is, Melocanninae, Racemobambosinae s.l.

Our results provide novel insights into adaptive for future ecological research.

ABSTRACT Aim In the present study, we focused in addressing questions concerning biogeographic history of Xanthium strumarium , an Old World native species whose close relatives are generally all to American continent. Location The distribution covers Eurasian continent and some African regions islands. Methods We employed herbarium material target enrichment (herbariomics) sequence data over 700 single copy loci estimate divergence times species.

Abstract Plant functional ecology research has primarily focused on juvenile and adult plants even though regeneration from seed can be the most consequential life‐history bottleneck with cascading influence later stages of growth reproduction. Understandings relationships among phenology, morphology growth‐related traits have improved our knowledge plant strategies adaptive responses to changing climate. However, whether phenological morpho‐physiological exist during is unknown. We also lack understanding relative importance these compared those phenology other factors like phylogeny, geographic location a species native or non‐native location. To better understand gaps in knowledge, we evaluated three (days germination, first third true leaves) six (seed mass, rate, root elongation root: shoot ratio, specific leaf area seedling C:N) associated for 131 forb globally distributed grasslands. Morpho‐physiological showed several significant correlations traits. Boosted regression trees revealed that their predicting varied (34%–51%). Interestingly, was comparable phylogeny (36%–46%). In general, faster phenologies produced seedlings grew faster. The strongest at germination (29%) decreased (8%–15%) stages. Native versus origin had little no impact (0%–2%) phenology. Strong between days indicate signatures local adaptation earliest life Similar trait values forbs imply matching may essential establishment. While associations not been previously recognized, results suggest are complex variable across regeneration.

ABSTRACT Problem Rafting is now recognised as a key process influencing the distribution and connectivity of several marine coastal species. scenarios are, however, often invoked in ways that do not account for clear differences biogeographic outcomes. Here, we illustrate value utilising multiple lines evidence (e.g. different life histories, ecologies, dispersal frequencies) elucidating historical, modern, future significance ocean rafting. We discuss these issues using range exemplar studies from Southern Ocean, where rafting clearly underlies many distributional patterns, although our conclusions hold generally. Explanations Such appear to be underpinned by variations life‐history characters, with, instance, direct‐developing taxa more suited long‐distance events might span generations. success also shaped diverse suite factors including durability raft, presence/absence resources competitors (intra‐ or inter‐specific) at destination, species' environmental tolerances, latitudinal movements position oceanographic fronts, frequency intensity extreme such storms. Several are influenced climate change, so detailed understanding their roles increasingly important—particularly distributions shifting. Future Prospects The Hemisphere—which has considerably than Northern Hemisphere (81% vs. 61%)—provides biogeographers with wealth information on processes, well intriguing examples puzzles still face. Powerful new tools, high‐resolution genomic analyses, ancient DNA, environmental, ecological modelling, providing granular picture biogeographical patterns.

ABSTRACT Seagrass beds are increasingly degraded; however, their protection and restoration still confined to localized marine areas, making it difficult establish connectivity between differently protected restored areas. One limiting factor is the lack of understanding processes mechanisms contributing seagrass population expansion at ocean area scale, which main driver dispersal via oceanic circulation. Coastal China. Taxon: Eelgrass ( Zostera marina )Using eelgrass as a model species, we propose strategy resequence samples from different geographical populations, analyze genetic structure seagrasses by combining genomics evolution, construct screen an optimal colonization history, calibrate timing events, thereby deduce evolutionary history populations. We constructed three‐dimensional hydrodynamic based on FVCOM numerical clarify seasonal changes in surface circulation patterns natural distribution areas precisely locate pathways populations differentiation. This study elucidated proliferation target physical driving provides theoretical basis for evolution restoration.

Abstract Although it is well documented that mountains tend to exhibit high biodiversity, how geological processes affect the assemblage of montane floras a matter ongoing research. Here, we explore landform-specific differences among based on dataset comprising 17,576 angiosperm species representing 140 Chinese mountain floras, which define as collection all growing specific mountain. Our results show igneous bedrock (granitic and karst-granitic landforms) correlated with higher richness phylogenetic overdispersion, while opposite true for sedimentary (karst, Danxia, desert landforms), clustering. Furthermore, landform type was primary determinant assembly evolutionarily older within climate greater younger species. study indicates not only affects richness, but also contributes composition floras. To explain differentiation propose ‘floristic geo-lithology hypothesis’, highlights role in floristic provides insights future research speciation, migration, biodiversity regions.

Abstract Honey bees are efficient pollinators of flowering plants, aiding in the plant reproductive cycle and acting as vehicles for evolutionary processes. Their role agents selection drivers gene flow is instrumental to structure populations, but historically, our understanding their influence has been limited predominantly insect‐dispersed species. Recent metagenetic work provided evidence that honey also forage on pollen from anemophilous species, suggesting vectors transmission genetic material not confined groups designated entomophilous, leading us ask: could act dispersal non‐flowering taxa? Using an extensive metabarcoding dataset Canada, we discovered may serve array sporophytes ( Anchistea , Claytosmunda Dryopteris Osmunda Osmundastrum Equisetum ) bryophytes Funaria Orthotrichum Sphagnum Ulota ). Our findings suggest occasionally aquatic phototrophs, specifically Coccomyxa Protosiphon species green algae. shed light broad resource‐access patterns guide plant‐pollinator interactions suggests flow, potentially even selection, across Plantae.
